Mikaella Castroneves’ Great Hair Day!

Indy 500 driver Helio Castroneves, who welcomed his first child with girlfriend Adriana Henao on December 28, shared a sweet photo of baby girl Mikaella on Twitter earlier today, with an exciting caption:

Mikaella turns 1 month old today! oohoo!!

He later added: “Mikaella was born with that much hair.. amazing! We are both currently looking for hair product sponsors! hahaha”

Three days before, the proud papa snapped a picture of his daughter taking a little nap on his chest. What a cutie!
